3 Claims. (01. 20-44) This? invention relates to silo structures and the like and more particularly to the. walls of such structures.

Several typesof farm buildings including silos are customarilybuilt in cylindrical shape and of ping adjacent edges which are adapted to. cover secure the .strips to the underlying wall.

Anotherobject of theinvention is the provision of .sheet metal strips which. are relatively narrow the nails, screws or other elements utilized to stantially flat to permit economical shipping.

. Still afurtherobjectof the invention is the prosuch amanner that theapplied strips will tightly grip the. underlying wooden orother type. ofwall structure. Not only is the underlying wall i overlapping the .edge of anadjacent strip this tight overlap. is made to bear upon the heads of nails, screws, or other fastening elements in the edge of the under stripso that said fastening elements are positively retained againstworking loose, and they are protected from the weather.

These and other objects and advantages of the invention will more fully appear from the following description made inconnection with the accompanying drawing wherein like reference characters refer to the same or similar parts throughout the views, and, inwhich:

Fig. 1 is an elevation of the lower portion of a silo with parts of thevertical wooden staves cov-v ered by my improved siding and otherportions of saidstaves uncovered;

Fig. 2 is an enlarged fragmentary vertical section through a silo wall showinga portionnof a c wooden stave andportions of overlappingmetal w strips; i i c Fig. 3 is an enlarged fragmenta horizontal section through a portion of a stave and the overlapping ends of the metal strips; I

Fig. 4 is an enlargedfra-gmentary perspective of 55 one of themetal'strips; and

and easy to handle;. and which are formed subvision .ofmetal strips for racing silos which are comparatively rigid. but .which may be bent around the curvedcircumference of silo .walls'in gripped-tightlybut with the edge of one strip Fig.5 is aview similar to Fig. 4with an angular corrugation inplace ofthe curved. corrugation,

1 shown in theother views I In. Fig. 1 there is shown asilo base 6 which is generally of concrete, and upon this base. is built a cylindrical silo structurewhose walls are indicated. as being made up of vertically arranged staves 'I which maybe or :wood and which usually are interlocked to. forrna tight wall structure. For the purposes of my invention the. wooden stave wall may be the'wallxof anold silo structure which is to be adaptedto my improved con I struction,- or it may be built up new. in the same general arrangement of woodenstaves.

Arranged circumierentially of the wooden staves! isaimetallic sheathing made up cf a plurality of. sheet metal strips 8 which as shown in Figs. 1 and 4, particularly, arev relatively narrow. and are. adapted to be placed around the wocdenvwalls. and secured thereto. by any suitable adaptedto be. driven through openings l0 in the upper edges of -the strips. 3-. Each of. the strips is PATENT I OFFICE r a 20 fastening. elements such as, nails: 9 whichfare 8 maybe. made long enough to. completely encircle i the silo. with its opposite ends overlapping, as

shownin-Fig. 3. Of course, if desired the strips 8. maybe made shorter so thattwo. or moresections of strips are used to eneircle the cylindrical wall :and in the latter case, of course, the. adja cent;;ends of strip sections, would overlap in the same manner as that indicated in Fig. 3. The strips are secured to the wall by first nailing one endjto the wooden staves and then bending the. strips which are preferably formed fiat so that said strips will assume the curvature of the wall.

Furthermore, the strips are longitudinally corrugated, as by the curved corrugations II, to give them more rigidity. The rigiditythus imparted\ to the strips tends to resist bending \movement to some" extent, and it has" been found that flatcorrugated strips of this type which are relatively long" and narrow will closely grip the wooden staves lyingunderneath when said strips are applied by first securing one end and then bending theremainder of the strip around the wall; The gripping action ofthe strips is comparable to that of bailing wire which will closely grip articles aroundwhich it is wound if such wire is bentin a slight curve with the convex portion of .the curved wire contacting the article being wrapped.

After the first or lowermost strip 8 has been placed in position around the silo wall and secured by nails or other fastening elements the next strip .is placed around the silo with the lower gripping of the second strip.. This second strip will not only tightly fit those portions of the staves with which it is in contact, but the overlapping portion of the lower edge of said strip which lies over the-fastening elements of the preceding strip willpositively confine said fastening elements against outward movement so that said fastening elements cannot work loose. In addition a weather tight lap-joint is produced and the fastening elements in the edge of the under strip are protected against the weather.

the

Succeeding strips are, of course, applied in same manner.

rugation I I, as best indicated in'Fig. 4, is positioned comparatively close to the upperedge of the strip 8, and it is so spaced from said edge that the lower edge of the next succeeding strip can he slipped downover the understrip just sulficient distance to form anadequate lap-joint and efiectively cover the fastening elements which secure the upper edge of the under strip to the vertical wooden staves.

In Fig. 5 the strip IZ is provided with angular corrugations l3 which are positioned similarly to the corrugations H in the strip 8 and function in thesame mannen These metal strips arepreferably made of identical shape so that they can be compactly nested -for'storage and shipment in flat form and then bent into position-on the individual silo wall as they are being secured thereto.

Ashas been brought out before the above described construction can be utilized for covering the walls of old wooden silos, or it can be It is preferredqthat the strips be made of galvanized metal to eliminate the need for painting, and the covering of the nails in the upper edges of the strips conceals practically all of the fastening elements which, in addition to protectingthe nails against the action of the elements, presents a silo wall structure of-improved appearance.

It will, of course, be'understood that various changes may be made in the form, details, ar-

, rangementand proportions of the siding strips without departing from the scope of my invention. y

' stantially flat, means for securing said fiat upper edgeportions to said supporting wall structure, and the lower edges of the next adjacent bands I overlyingthe upper secured edges of said bands. It should be noted that the upper rib or cor- 2. In a silo construction and the like, a subwall covering elements comprising a plurality of elongated, strips positioned circumferentially of said wall "structure to provide substantially continuous circumferential bands, longitudinal corrugations spaced inwardly from the edges of said bands; the areas between said corrugations and the edge areas of said bands being substan-' tially flat, nails extending through said substantially fiat upper edge areas and into said supporting wall-structure, and the lower edges of upwardly adjacent bands overlying the upper nailed edgesof said bands, and said corrugations being so spaced from said upper edges that a predetermined constant overlap is produced.

' 3. The method of securing elongated circumferential bands to the walls of silos and the like,

which includes applying said bands successively by firmly securing one end of a band to the silo wall, bending the band around the silo to conform to the shape thereof andtightly grip the Walls thereof, securing the other end of said band to said silo positively securing only the upper edge of said band to said silo, and then applying successive bandsin the same manner with the lower edge of the next successive band overlapping the upper edge of the preceding band and its upper edge securing means, whereby each band will have a gripping action upon the underlying silo structure and will also retain the said upper edge securing means against outward displacement.
